IMPROVEMENT IN BRICK-MACHINES.

Specification forming part of Letters Patent No. 13,400, dated February6, 1872.

To all whom it may concern:

Be it known that I, HENRY J ONES, of Fort Madison, in the county of Leeand State of Iowa, have invented a new and Improved Brick- Machine; andI do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, reference being had to the accompanying drawingformingpart of this specification.

The invention will be first fully described, and then clearly pointedout in the claims.

Figure 1 is a side elevation of my improved machine, with a part brokenout. Fig. 2 is an end elevation, partly sectioned. Fig. 3 is a sectionon the line 00 a; of Fig. 1, looking in the direction of the arrow 1.Fig. 4 is a section through the mud-mill and conveyer on the line 313 ofFig.2. Fig. 5 is a partial section on the line 2 z of Fig. 1. Fig. 6 isa side view of a section of the mold-wheel. Fig. 7 is a section of Fig.6 and Fig. 8 is a section of the mold-closers and the chain by whichthey are attached, the section being taken on the line a a of Fig. 3.

Similar letters of reference indicate corresponding parts.

A is the case of the mud-mill, B the mixingknives, and O the shaftwhereon the knives are mounted, said shaft being arranged horizontallyand geared at the outer end by a pair of spurwheels, D, with a longshaft, E, extending under the machine fiom the other side, and gearingwith the driving-shaft F by the wheels G H 1 K. This shaft E also drivesthe large moldwheel L by the pinion M. The said knives B arestrong,thick, S shaped arms of steel ,mounted at the center on theshaft, and they are provided with sharp cutting-edges N on the advan cing sides, calculated to cut and displace the sticks, roots, and the likesometimes contained in the clay. As many of these arms will be put onthe shaft as required. They are beveled on the sides, which will workthe clay along toward the mold-wheel, and at the inner end of themold-case a spiral conveyer, O, is applied to the shaft, to take theclay thereat and convey it through a plate, P, into the molds P of themoldwheel, which is turned slowly and continuously along past the saidplate. These molds, so filled, are moved along by the turning of thewheel along up in front of the mold-closers Q,

jointed together in an endless chain, which is suspended on anelliptically-shaped support, It, therefor, proj ectin g from the innerface of the housing S, within a recess, in which support is a toothedwheel, T,,mounted on a stud, U, and receiving the rollers V of thepivot-pins W, by which the said closers are jointed together in a chain,in the notches between its cogs, to control the action of the chain.These pivot-pins have other rollers, X, on the other ends to work overthe surface ofthe support R, and the flanges Y have studs between thepivot-pins for other rollers, 00 to bear on support R. The faces ofthese closers are parallel with the side of the mold-wheel, and theyhave a flange, y, perpendicular thereto, by which they are jointedtogether by the pins W. They also have another flange, 2, parallel with3 but a sufficient distance therefrom to admit of arranging thefriction-wheel a between them. These wheels to, in the upward movementof the chain, come in front of the inclined plane I) of a bar, I),supported in side of the housing S on the cross-bars k, and arranged forcausing the closers to press firmly against the side of the wheel tosustain the force of the pressers, which act at this time. These closershave pins X projecting from the pressing-face and taking into a notchbetween the teeth of the internal rim X which causes the chain to movewith wheel L. The said press ers d, which are blocks of the same size orslightly smaller than the molds P, have plates 0 attached to them, whichare fitted to slide back and forth in under-cut grooves fin aflange,g,on the side of the wheel L opposite to the moldclosers, which groovesallow the pressers to move into the mold-spaces P. The said press erscarry friction-wheels h mounted between the flangei and plate 0, which,being carried by the rotation of Wheel L along against the inclinedplane of the bar j mounted on the cross-bars k stretching from one tothe other of the housings S S, force the plungers in against the clay,pressing it against the moldclosers Q, thereby forming the bricks. Afterthe molds with the formed bricks in them pass beyond the closersthepressers come in contact with the inclined face of a bar, I, supportedon the cross-barsm, by which the bricks are forced out upon an endlesscarrier, n, on suitable cylinders, and operated by a pinion,-p, on onegearing with the toothed rim X The bars I) and j, having the inclinedfaces for forcing the mold-closers and the pressers toward the wheel,are clamped to the crossbars k by bolts passing through slots in saidbars, so as to be adjusted toward or from the wheel, and they aresupported against shifting back by screws .1, and the bars k are boxedto the housings so as to effectually hold them against spreading. qrepresents rollers supported in adjustable studs 1' in the lower part ofthe housing S, so that the wheel L will bear against them at the sideopposite to where the mud is forced into the molds, and be supported bythem against the lateral force sustained at this point in consequence ofthe forcing of the mud in. t is a curved plate attached to the housingS, just above the rollers q, for arrestin g the backward movement of thepressers caused by the mud being forced against them, they being in theposition in the molds in which they are left after discharging thebricks. This plate is supported by adjusting-screws w, for regulatingit, so as to stop the pressers exactly at the right point.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination, with the mold-wheel, of the chainof mold-closers, the pressers, and the curved bars j b with inclinedplanes, all operating substantially as specified.

2. The combination, with the mold-Wheel and pressers, of the curved barland the endless carrier at, substantially as specified.

3. The mold-closers Q hinged together in an endless chain by the flangesy and pins W, and the latter provided with rollers V and X, and thewhole combined with the support R and wheel T, substantially asspecified.

4. The mold-closers having the pins X arranged for gearing with thetoothed rim X substantially as specified.

5. The bars b, j, and Z, bars k and m, housings S S, andsupporting-screws X, arranged substantially as specified.
